Splashtop Inc. - Splashtop Remote
Full audio support and only $5 as opposed to the $15 or $30 for the others out there.
I ran two citrix servers and five clients...from the phone.
And to top it off...3g/4g outside WiFi access...
How do I connect to my home computer outside from home via remote network or 3G? : Splashtop Remote - Support
